Panchromatic remote sensing image with high spatial resolution has been applied in military reconnaissance, ground surveillance and other areas. A simulation method for high spatial resolution panchromatic remote sensing image is presented .The data source of the simulation is a kind of the airship remote sensing image. The low-altitude wide-field images were classified according to typical surface features. Then these images and the multi-spectral images were fitted to different typical features. The high spatial resolution panchromatic simulation image was composed by the fitting results. The simulation precision was assessed. Compared with satellite panchromatic remote sensing images, high spatial resolution panchromatic simulation image has the same spatial resolution, panchromatic band, wide view and so on. This method provides accurate data source for the satellite panchromatic remote sensing image simulation.
